GEORGE E. NOBRlS, OF TROY, ASSIGNOR OF,ONE-HALF TO JAMES K. P. PINE, -OF LANSINGBURG, NEW' YORK.

QLLAR-FOLDING MACHINE.

SPECIFICATION forming part of Letters Patent NO. 341,044, dated May 4:, 1886.

Applieatioh filed December 26, 1684. Serial No. 151,154. (No model.)

To all whom it vmay concern:

Be it known that I, GEORGE E. NoRRIs, of the city of Troy, county of Rensselaer, State of New York, have invented a new and useful Improvement in Collar-Folding Machines, of which the following is a specification.

My invention relates to a mechanism for folding the edges of collar and cuff blanks preparatory to the uniting of such edges in the manufacture of collars and cuffs; and the object and purpose of my invention is to produce uniformity in the finish and edges of the articles thus made, and to do by machinery rapidly what is but slowly done by hand.

My invention consists, as will be more fully detailed hereinafter in connection with its illustration, in the combination, with a hinged holder-plate that upon both ends and one side has a form coincident with that of the collar or cuff blank to be folded, and which holderplate is adapted to receive, hold, and press down on the upper face of the collar or cuff blank so as to hold it firmly on a folding and creasing bed, with the edges of the blank subtending the edges of said holder-plate, and a folding-plate arranged in a plane parallel with the holder-plate and on the same bed, said folding-plate having a cut-out area similar in form to, but larger than, the holder-plate, the outer edges of the holder-plate and the inner edges of the cut-out area of the folding-plate being in the main parallel, said folding-plate being actuated to slide over at intervals of opposite motion the ends of the holder-plate, and also at an intermediate period of motion over one side of the latter, so as to turn down and fold over the end edges and one side of said holder-plate the subtending end edges and one side edge of the collar or cuff blank, as held by said holder-plate.

My invention further consists, as will be more fully detailed hereinafter in connection with its illustration, in the combination of a hinged holder-plate for receiving and holding a collar or cuff blank firmly upon a bed, a folding-plate adapted to turn over and down the end edges and one side edge of a collar or cuff blank by the motion of said folding'plate over the edges of the holder-plate, and a steam chest or inclosure connected with and f0rming a part of the bed on which said foldingplate and holder-plate are arranged to operate.

My invention also consists, as will be more fully detailed in connection with its illustration hereinafter, of a mechanism adapted to press with hot surfaces the edge-folded blanks.

My-invention also consists, as will be more fully detailed hereinafter in connection with its illustration, of a mechanism for connecting and automatically disconnecting power to operate the apparatus.

My invention also consists in the subcombination of the parts of the mechanism which I illustrate, where the same performs specific function, as will be designated in claims.

Accompanying this specification, to form a part of it, there are twelve plates of drawings, containing twentyeight figures illustrating my invention, with the same designation of parts by letter-reference used in all of them.

Of these illustrations, Figure 1 shows a perspective of my improved collar-folding machine, with the hinged holder-plate shown as turned up, and a blank being inserted between the under surface of the holder-plate and the fingers arranged thereon to hold the blank. Fig. 2 shows a combined side elevation and vertical section of the mechanism. Fig. 2-2 is a detail sectional View taken on the line m a of Fig. 10, showing the dog with its screw end resting against the frame and its point against the finger of the holder. Fig. 3 illustrates a plan view of the top of the machine, the holder-plate being shown as turned down upon a collar-blank, with the actuating mechanism omitted, as well as the arm which presses down upon the holder-plate. This view illustrates the relative position of a blank as held by the holder'plate, and with the folding-plate as moved to fold down the edge of the blank at one end over the holder-plate, a dotted line indicating the portion of the blank that is below the holder-plate and the folder. Fig. 4 shows a plan view of the folding-plate, the top of the bed, a cam-groove arranged in a roller that is on the driving-shaft of the machine, and a cam-pin on the folding mechanism connecting with the said cam-groove for actuating said folding apparatus to move across and back from over the ends of the blank-holder.

Fig. 5 shows a top view of the folding-bed of the machine, with the folding-plate and a part of its frame removed or broken out. This figure illustrates the position of the bar arranged beneath the folding mechanism, and which, by means of a cam-pin on the end of the bar an'da cam-groove in the end of the cam-roller operates the folding mechanism to move across and back over the side edge of the blank-holder plate. This figure shows also a guide arranged .on the before-described cam'pin bar, this guide being arranged to project upwardly through a slot made in the folder-frame. Fig. 6 illustrates the bar shown in Fig 5, also a part of the folding-bed, and the guide for the side-to-side motion of the folder mechanism, part of said guide between its ends being broken out. Fig. 7 is a section taken on the line at xof Fig. 5.Fig. 8 is a section taken on the line 00 00 of Fig.5. Fig.9 shows an enlarged elevation of the holder-plate, it being illustrated as turned up on its hinged connection to show the fingers and blank stops on its under surface. This view shows also a part of the folding-bed of the machine, and also a part of the bar moving thereon to operate the folding mechanism to move across and back from over the side edge of the holder-plate. Fig. 10 shows an enlarged plan view of the top of the holderplate and its frame, and in position appearing as when down on the folding-bed, and as detached from the rest of the mechanism. Fig. 11 shows asection taken on the line x m of Fig. 10. Fig. 12 illustrates in a perspective the forked end of the presserarm and its bearings. This figure shows also a cam-pin on one of the bifurcated ends of the presser-arm adapted to run in the cam groove formed in that end of the cam-roller on the driving-shaft of the machine which is opposite to that in which is formed the cam-groove to operate the folder mechanism. Fig. 13 illustrates one of the presser-fingers, which are adj ustably attached to the opposite sides of the machine-frame, having their ends curved downwardly and inwardly, so as to be in contact with the upper surface of the folding-plate. Fig. 14- shows the mechanism by which the outer ends of the presser-fingers are adjustably connected to the opposite sides of the machine-frame, so as to regulate the pressure of the finger ends upon the foldingplate. Fig. 15 is an enlarged perspective ofa crankarm and roller arranged on the end of the driving-shaft to operate the hot pressing mechanism. Fig. 16 is a perspective of the hotpressing mechanism composed of an upper movable plate made with an upwardly-projected forked standard and a lower bed con sisting of a steam-chest. Fig. 17 illustrates a side elevation of the hot pressing mechanism with the upper movable plate thereof tilted up on one side for the entrance of a collarblank between its two pressing-surfaces, showing also the engagement of the forked standard of the hot-presser mechanism with the roller on the crank-arm of the driving-shaft. Fig. 18 illustrates in a side elevation the hot presser mechanism with the upper plate thereof shown as down on a blank placed between it and the steam-chest, and the crank-arm roller represented as having passed from its engagement with the forked standard. Fig. 19 represents in aside elevation the hot presser mechanism with its upper movable plate tilted over, so as to allow the pressed blank to pass out therefrom, and showing also the engagement between the forked standard and the roller on the crank-arm of the drivingshaft of the machine by which the hot-presser mechanism is so operated. Fig. 20 isaside ele vation of the cam-roller on the driving-shaft and the cam-groove formed therein,which operates the folder mechanism to move from side to side over and from off the ends of the blank-holder plate. Fig. 21 is a horizontal section of the roller, taken on the line 00 x" of Fig. 20. Fig. 22 is a view of one end of the cam-roller shown at Figs. 20 and 21. This Fig. 22 illustrates the position of the camgroove in one end of the cam-roller that by means of an engaging cam-pin on a bar moves the folder mechanism over and from off the side edge of the holderplate. Fig. 23 is an end view of the same cam-rollershown in the three preceding figures, and this illustration shows a cam-groove in that end of the roller which is opposite to that shown in Fig. 2, the cam-groove represented in this figure (23) being that which operates the presser-arm to descend onto and arise from off the blankholder. Fig. 24 is a plan view of the clutching mechanism by which power is communicated to the driving-shaft of'the machine. Fig. 25 is a longitudinalsectionalcentral view taken on the line m 00 of Fig. 24. Fig. 26 is a section of the clutch, taken on theline 00 as" of Fig. 24.. Fig. 27 is a cross vertical section taken on the line z z of Fig. 24:.

The parts of the mechanism are designated by lettersreference, and their function is described as follows:

The letters F designate the. frame of the machine, which, at the top, is made to incline from the front downwardly and rearwardly.

The letter B designates the foldingbed formed by the upper surface of the steamehest O, which receives steam from the steampipe 1), to heat it.

The letter H designates the blankholder, which is hinged to the frame at h, and on such hinged attachment is adapted to swing down onto or up from off the bed B.

The letters f and f indicate fingers arranged on the hinging-shaft, to press against the under surface of the holder or a blank placed against said under surface when the hinged blank-holder is swung down 011 the folding-bed.

The letters (2 designate dogs, that at d are pivoted to the blank-holder hinging-shaft bar on its outer face, the inner curved ends of these dogs being arranged to press on the outer faces of the fingers f, and the lower ends of these dogs are provided with outwardly-projecting set-screws d'*, as shown in Figs. 2, 9, and 10. These dogs at their setscrew ends are arranged to engage with the front edge of the machine-frame at 61* when the blank-holder is turned up, they being at their other ends so moved on their pivots as to press the said fingers away from contact with the under surface of the holder H for the insertion of a collar-blank between said holder and fingers, as shown at Figs. 1 and 22. The set-screws on the ends of the dogs, as they are screwed out or in, regulate the extent at which the dogs shall press upon the fingersf to move away the latter from the holder.

The letter f designates a centrallyplaced finger having the same function as the fingers f, but which is forced away from its contact with the under face of the holder as the latter is turned up by the contact of said central finger with the cross-bar a on the U-form arms a a, the latter being arranged on the machine-frame so as to curve around the rod 1*, the bar a coming in contact with said central finger when the holder is turned up.

The holder-frame H and the blank-holder H are turned up on their hinged connection with the machine-frame by the action of a grooved pulley, p", on one end of the holder frame hinging-rod r, acord, 0, attached to the said pulley and adapted to wind up in said pulley-groove, with a weight, 10, attached to the lower end of the cord.

The holder-frame and connected holder are forced down onto the bed 13 by the operator by means of the handles h".

The letter 0 indicates a cam-roller, arranged on and so as to turn with the driving-shaft of the machine. (Indicated at S.) The circumferential face of this cam-roller, upon one ofits diametrical halves, is made with the Sform cam-groove O, which cam-groove in continu ity joins with the directly encircling camgroove 0 on the opposite circumferential half. of said roller. The S-form canrgroove O, as produced in one diametrical half of the roller 0, is made with the oppositely-reversing offset-curves Z, Z", and Z, with an intermediately circumferentially-direct groove part Z, the function of these opposite curves in the the cam-groove being to engage with a canr pin on the folder mechanism to move the lat ter from side to side, over across, .and from off the opposite end edges of blank-holder.

The letter K indicates a cam-groove formed in one of the ends of the canrroller O, and this canrgroove K is adapted to engage with a cam-pin upon a bar connected to the folding mechanism, so as to move the latter over and across the side edge of the holderplate.

The letter K indicates a cam groove produced in the end of the roller 0, whch is opposite to that which moves the folder meclr anism, the said cam-groove K being adapted to operate the pressenarm, as will be subse qu ently described.

The letters N designate the folding-plate, and N the frame to which the former connects,

the two constituting the folding mechanism. This folding-plate N is made with the cut-out area A, which in form mainly corresponds upon its two ends, and one side with that of the blank, the edges of which are to be turned over, and it in form upon its two ends and one side also coincides with that of the blank, the edges of which are to be turned over; and it in form upon its ends and one side corre sponds also with the form of the holder-plate, only that the cut-out area A is larger than the holder-plate. This cut-away area of the folding-plate at the corners near where its end and side edges meet is made with the lap-fold slits o o, the use of which will be subsequently detailed.

From the rear side ofthe folding-plate frame N there projects a cam-pin, P, adapted to run in the S-form cam-groove G, and the connecting circumferentially direct cam-groove 0 made in the opposite side faces of the camroller 0. n

The letter G indicates a guide-bar that is stationary when the foldingplate is being passed horizontally from side to side, over and from off the ends of the holder-plate, there being a slot, y, made in the folder-plate frame N for its reciprocating side-to-side passage along said guide G. \Vhen the folding mechanism is moved across the side of the holderplate, then the guide-bar moves with the fold ing mechanism, as will be subsequently described herein, in connection with the mechanism that thus operates the folding plate and frame.

The letter D designates a bar that is attached to the rear side of the folding-plate frame, and also to the guidebar G, on the under side of the latter, so as to move with it, as indicated at Fig. (5, said bar D having at its inner side near its outer end where projected rearwardl y beyond the folderpla-te a frictionroller, m, arranged upon a pimp, projected therefrom, the said friction-roller being adapted to run in and be operated by the end camgroove, K. \Vhile'this roller mis moving on that part of the said cam-groove K forming a true circle in the end of the roller 0, it does not actuate the bar D; but when in the move ment of said friction-roller it reaches that part of the said end cam-groove, K, which is made with a curve, (i that varies it thereat from a true circle, then the engagement of said friction-roller m therewith horizontally moves the said bar D, connected guide-bar G, and the attached foldingplate frame and foldingplate, so that the side edge, 0, of the cut-away area made in the said folding-plate passes over the side edge, 0, of the holder H, and then in reciprocation returns therefrom.

The bar D, as before described, is connected with the guide-bar G, and the latteris projected up through the folder plate frame through the slot 3 the latter being made enough longer than the guide-bar to permit of the lateral side-to-side movement of the folder mechanism; but when the bar D is moved by 4 8&1 0 14:

the engagement of its pin 12 and roller m with the end cam, K, then the bar D, being at tached at right angles to the guide-bar G and the latter projected up through the slot by this connection moves the folder-frame and folder-plate in reciprocation from the rear to the front ofthemechanism,as before described.

The letter E designates a presser-arm, made at its rear end with the bifurcating branches 6 6 which branches are each made to have on their outer sides a trunnion-bearing, t, the said trunnions being located on the outer sides of the branches in advance of the rear ends of the latter.

The letters bdesignate bearings for the said trunnions to journal in, and which bearings are above the bearings b of the driving-shaft S. The yoke of the presser-arni is mounted in its bearings with the inner face of the branch 0 set against the face end it of the cam-roller O, and the other branch, 6, arranged with the roller w", fixed on its inner face in the camgroove K in the face end a of the cam-roller O., This cam-groove K produced in the end face, if, of the roller 0, as shown at Fig. 28, has a part of it forming a true circle and a part (indicated at a) which curves inwardly therefrom. When the roller 10 on the branch 6 of the presserarm E reaches this incurve a of the cam-groove K, it raises the presser-arm from off the holder, and so soon as the wheel 10'. reaches that part of the caurgroove forming a true circle the presser-arm is returned to press on the top of the holder.

The letter I indicates the hotpresser, which is made with the steam-chest i, adapted to receive steam by means of the pipe 1), the top of said chest forming the presser-bed 73*.

The letter It designates the movable plate of the hot presser, and which is arranged on top of the steam-chest t, and both of which in parallel coincidence are arranged to incline downwardly-and outwardly from the front. This plate It has projected from its upper surface a forked standard, U.

The letters 7c designate pins vertically projected from the upper surface ofthe steamchest 2', near the corners of the latter, the steamchest being slightly larger in its top than the movable plate It, and the letters k designate pins projected from the ends of the movable plate R, near their corners, and so arranged with reference to the vertical pins k in the steam-chest that when the movable plate is in position the horizontal end pins on the lower side of the latter shall be inside of the vertical pins on the steam-chest, and the horizontal pins It ofthe movable plate R on the upper or front side of the latter shallbe outside of the vertical pins on the upper or front side of the steamchest. As thus arranged the movable plate may, as held by the pins, as shown at Fig. 18, be tilted up from the upper side for a blank to slide in between the movable plate and u steam-chest, as shown at Fig. 17, and then be tilted upwardly on the lower side for a blank to slide from off the steam-chest, as indicated at Fig. 19, and out from between the latter and the movable plate.

Fixed on the end of the driving-shaft S is a crank-arm, J, having a pin, a, projected outward from its free end, which pin is provided with a roller, 5*, substantially as shown in Fig. 15. The office of this crank-arm is to tilt the plate R on the hot presser, which is done as follows: When the crank-arm is carried around by the shaft, the roller 1) comes in contact with the long arm of the fork O substantially as shown in Fig. 19, and lifts the lower edge of the plate up, as shown; thence the crank-arm continues in a downward move ment, easing the plate until it assumes its closed position, when the crank-arin moves across the space between the forks and engages with the short projection 0* on the short prong of the fork and raises the plate from its upper side, substantially as shown in Fig. 17 of the drawings.

The letter P designates a loose pulley arranged on the drivingshaft S, said pulley being provided on its inner face with the clutch ing-pins 19 The letter M designates a flanged sleeve ar-' ranged on a feather, f, upon the driving shaft S and adapted to slide thereon, but which sleeve, on account of the construction of the feather f*, that tongues into it, is made to turn with said shaft. The letters Z Z indicate two rim-flanges projected outwardly in revolution from the ends of said sleeve M, and the let ters L designate a curved lever that is pivoted centrally at '0 to an arm, 9, on the machineframe F. The letter T designates a roller arranged on one end of this curved lever, and which roller is constructed to be held in engagement with a curved cam, V, on the driving-shaft of the machine by means of a spring, 8. The end X of the lever L is forked so as to produce the ends e a, each of which is constructed with and pivoted to a bearing-block, n which blocks are adapted and arranged to journal at 2" on opposite sides of the sleeve M between the flanges Z Z The letters M" designate clutching-pins arranged on that end face of the sleeve M which is adjacent to that end face of the loose pulley P which is also provided with clutchingpins.

The letter W designates a crank-shaft that journals into the machine-frame F atjj, and the letter 6 indicates a cam arranged on said crankshaft, which cam is constructed to pass under the driving-shaft S and cam V, and when thus operated by said crank-shalt to throw upwardly the end of said cam V, so that the spring 8 may force inwardly the inner end of the lever L, and thus to bring the roller r into contact with that part of the cam V which is near the shaft S, and thus force outwardly the other end of said lever L, bringing the sleeve M and its pins so that the latter will engage with the pins of the loose pulley P to start the mechanism. \Vhile the roller r on the end of the lever L is running on that part of the cam V which is nearest to the shaft S, the lever L forces the sleeve M and its pins to engage with those on the loose pulley, and the latter operates the machine. lVhen, however, the roller 1" on the lever L, as held against the cam V by the spring 8, reaches the upper outer end of the prolongation of said cam designated at c the sleeve and pins are moved inwardly from an engagement with the loose pulley, and the machine stops after having made one complete revolution. When stopping, the roller 1' on the end of the lever L, rests on the upper side of the extreme end o of the cam V,to be started, as before described, by the crank-shaft W and cam The cam-groove Kiin the end of the roller 0, is arranged on the latter so as to have the presser-arm E raised from off the holder when the machine has completed its revolution and the roller 0 stops, and the relative position of the curve d in the cam-groove K in the end of the roller O'is such asto have the bar D and cam-pin p in that portion of the groove forming a part of a true circle when the roller stops,so that the folding mechanism shall be from off the side edge, 0 ,of the holder. The position of the cam-groove O and 0 in the roller 0 is such that the cam-pin P will be in the circumferentially-direct cam-groove G and the folder-plate connection with and 0perated by said pin from off and about equidistant from the ends of the holder-plate when the roller 0 stops.

The letters indicate fingers that are adjustably attached to the sides of the machineframe F by means of set-screws i These fingers are made to curve downwardly from where attached, so as to press on the upper surface of the folder-plate N, their function being to keep the latter down closely on the ends of the blank being folded, while the superimposed folding-plate is passing over said ends of the blank and ends of the holder.

The letter T designates a table at the front of the machine, and a a slideway running therefrom on an incline downwardly to the upper edge of the hot pressing mechanism for the blank to slide on down to the latter, said slideway being shown at Fig. 1 and in part by a dotted line at Fig. 2.

The mechanism thus constructed is operated as follows: The holder-frame H and the holderplate H being turned up by the pulley-weight w, the fingers f and fingers f having been forced away from their engagement with the under side of the holder plate by the dogs d and the bar a a collar-blank is inserted beneath said fingersf, so as to be between them and the holder-plate, the lower edge of the blank resting on the stops of, with the parts appearing as shown at Fig. 1. The holder plate and frame are then turned down, and when this has been done then the crank-shaft W is forced down, and which serves to connect the coupler mechanism, as before described. This actuates the roller 0 and the cam-pin P to run in the curved part Z of the cam-groove O, and which moves the folderplate N so that its cut-out area A, where parallel with the end of the holder-plate, moves over one of the end edges of the latter and the blank,and while the pin P of the folder mechanisrn is in a succeeding movement passing through the circumferentially-direct part of the said cam-groove G, where indicated at 1, then the cam K is arranged to operatethe folder mechanism to move back and forth, so that the side edge of the cut-out area A passes over the side edge of the blank and'the holder-plate. Soon as this has been done the cam-pin P is moved by the curves Z 1 of the cam-groove O to pass the folderplate sidewise, so as to have it move over and from off the other end of the folderplate and the blank to turn down the remaining end edge of the latter. Then each end of the blank is being folded thereat, the slots '0 of each end receive to turn over and down the folds made in the corners of the blanks. When the machine starts, and before the cam-pin P commences to operate the folding mechanism, the cam K in one of the roller ends forces the presser-arm E down on the holder-plate to continue there until the folding of the blank edges is completed, when the presser-arm is raised from off the holder-plate. After the blank has been thus folded, the holder is raised, the folded blank removed, and an un folded one inserted as before. The folded blank, after having been taken from the holder, is passed from over the table T, so as to slide along down the inclined sideway 12* to the hot pressing mechanism. At each revolution of the crank-arm J on the shaft S, the movable plate R is tilted up to receive a blank, to descend upon it to press it, and is tilted up on its lower side to allow the blank to pass out from under the plate and to slide along the incline w to the receptacle Z beneath the machine.

The central finger, f, may be omitted.

While I have shown springs s" as connecting the movable plate R with the machine-frame, said springs may be dispensed with by making said plate R heavy enough to fall promptly by gravity after having been tilted up.

\Vhile I prefer to heat the bed B and the hot pressing mechanism by steam, yet the heat used may be produced in the folding bed and the hot pressing-bed by any other well-known means.

While I have shown the folding-plate made with the slots 12 at the corners of the cut-out area A, if desired, the folding-plate may be made without them.

As the combination of a presser-bed and a hinged holder plate adapted to receive a blank, as shown, and made larger than but in a form coincident to that of the blank to be folded, and a folding-plate made with the cutout area A coincident in form to but larger than the holder-plate, would, if operated to slide over one end of the holder-plate and blank and then over one side of the blank IIO and holder-plate, and then in sequence over the other end of the holder and blank in so operating, would perform the same useful function whether actuated by the arrangement of cams and cam-pins shown or any other equivalent means which would operate them in the same way; hence I do not limit my invention of the combined holder and folding plate, as they are shown to be made to the specifie means used to operate them.

I/Vhile the work of folding and creasing the folds into the blanks is better done by heating the bed of the folding mechanism, and also that of the pressing mechanism, yet the latter and the folding-bed may be used without heat, if desired.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
